New levitating helecopter

They fly only because they "beat the air into submission". Problems with the blades........auto rotate & come down softly I'm told.

I believe that depends on the design - some are auto-gyros and some are not.

I was thinking that it was a strobe type effect but looks more like editing in post but I could be wrong. I have seen numerous examples from car wheels to centrifuges where specific RPMs and patterns can cause a visual effect that fools your eye/brain into thinking the object is either not spinning, or spinning backwards, or spinning at a rate other than the true rotational speed.

There was a program on awhile back - might have been the Mythbusters but I think it was something else - where they showed old movies where the wagon wheels appeared to be spinning counter to the rotation caused by the carriage moving forward and they were "testing" to see if this was an artifact of the way the camera/film captured the image or if it was observable directly without the intervention of a camera. I could have told them without doing the experiment that I have seen plenty of examples without camera or film involved. They did conclude that such phenomenon can be observed directly.

With the helicopter - I would have expected a bit more blurring or some precession of the blades as - but if there was an artificial light source used or manipulation of the camera capturing the footage that could explain it.
 
Im am a vet with about 4000 hours in helicopters as a pilot and as an instructor. Please believe me when I say I would much be at altitude in a helicopter if the engine fails than an airplane. Many factors enter into a successful emergency landing, but that is usually the case in any emergency.
 
Ever watch those old westerns with stagecoachs whipping down the trail what looks to be 55 mph? The wheels are always spinning backwards! Remember those free spinning wheel looking hubcaps that came out about 20 years ago? First time I seen one I was at a intersection and a car was sitting at the red light from my right. I focused on the wheel spinning and had a fast impression that the car was moving but it was sitting still. I stood on my brake! I wonder if they were ever outlawed anywhere for that?
I would like to try flying a copter but probley couldnt afford a lesson. There is a school at our airport with about 13 copters. It started up about a year or two ago here at cedar city. I understand most if not all students are vets on the GI bill. I heard the course is about $150,000s! Thats a lot of dough shelled out if you ever did get a job and then a heart attack or something to lose your physical! I was out earlier today and flew my citabria about a hour and usually could see one to three copters at a time hovering around the airport. They are flying over our house more times a day than I can count.
Back in 1960 I was working on a fire in Sequoia NP. A pilot had to get a bunch of us off the mountain side quick as the fire was coming on us fast. We were on a high cliff with some trustee`s. I flew down with one, he had long hair. The pilot got a short ways out from the mountain and I guess auto rotated down quite a ways. I looked over and seen the trustees hair standing straight up about 10"s. We were sort of free falling and it felt like we were going to hell on a toboggan! Actually it cracked me up looking at him! Later that afternoon that pilot crashed! He lived but was busted up. I was on the heliport when another pilot brought him in strapped to the runners. I understand he was hovering while they were unloading some tools on the steep mountain side and a gust of wind caught the copter and rolled him over down the mountain. It was a huge fire with about 10 contract pilots. We had a army medic on the field and he had to pull some teeth out of the poor guys throat! Had a busted leg too.
Another pilot that I later recognized on Broderick Crawford`s Highway Patrol series had flown me up earlier on that same fire. A few years later I ran into Crawford when I was a universal studios guard. I asked him about the pilot and Crawford told me that he later got killed when he dropped into a fire! I had a close friend that I worked with that was a HC instructor out of Burbank. One night he called in sick. The next morning when we got the newspaper there was a nice picture of him in the LA Times! He and a student had to auto rotate down right in front of a funneral being held at forest lawn! They were using Bell G-2`s and G-3`s back then. Also a Hiller and a french Allouett. (SP?) We also lost another copter that summer in 1960.
 
Does the term "timing light" mean anything to the rest of you old-timers here? Remember how you were able to see that timing mark?

Just make sure you had it hooked to the right spark plug wire, or you could mess up your engine for sure! Ask me how I know...
 
I've worked with tachometers for measuring RPM's of HVAC fans, especially squirrel cage types, and it sends out a strobe light that makes the fan blades appear to "stop" when adjusted properly.
The term for this tool is a Stroboscope. It has a calibrated internal clock that flashed the light at a particular rate. It is a great tool for determining the rate of rotation of anything that spins.

High quality turn tables (record players) had them built in. They used the line frequency to strobe the light and a series of dots painted on the turn table to ensure an accurate 33 1/3 or 45 RPM spin rate.

A timing light is exactly the same idea as a stroboscope except for how the light is controlled. Instead of an internal time source, its flash was triggered by induction from a spark plug wire.

Just like DR505 said, get the wrong wire and the timing will be off.
 
I did get some stick time in an E Model Huey...was a USMC gunship once. I have to admit, flying it was 2 tons of fun!
